annnnnd here we have an attempt to pinpoint the all-important brew temp. warning: this clip will give you a rightward-leaning neck-crick. forgive me. i was pulling the lever with the right hand, securing the cup fitting with the left and shooting video with my chin and sternum.
video here.
this would seem to indicate that a 1,2-bar boiler pressure reading (the case here) is not exactly the same proxy for temperature as with the isomac (with the big momma, that’s right about my ideal brew temp — after a cooling flush, of course). in this case, the brew temp would appear to be just over 205 degrees, even after several rapid-fire pulls of the lever. wonder if there’s an adjustment screw somewhere….
